What is the reasonable domain for Leslie's car that travels about 25 miles per gallon and needs 14 gallons of gas to be full?

Back

Front

What is the range of the function y = 3x if Hector wraps between 25 and 30 presents?

Back

The range is {75, 78, 81, 84, 87, 90}.

Front

If f(x) = 6x - 18, what is x when f(x) = 0?

Back

x = 3.

Front

What is the domain of the function y = 3x for Hector's goal of wrapping between 25 and 30 presents?

Back

Front

What does the notation 1 < f(x) < 5 represent in terms of a graph's range?

Back

It indicates that the output values of the function f(x) are between 1 and 5.

Front

Define 'domain' in the context of a function.

Back

The domain is the set of all possible input values (x-values) for which the function is defined.

Front

Define 'range' in the context of a function.

Back

The range is the set of all possible output values (y-values) that a function can produce.

Front

What is the significance of the equation y = mx + b in linear functions?

Back

This equation represents a linear function where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Front

What is the formula to find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.
